not too sure.. but she can try & call her mobile phone
provider for more information if the sms is stored in SIM card.. if
is stored in HP memory, then she has to call the mobile phone
company, if is stored in external memory, likewise.. call the
external memory company for help..
but if she is gng to the police station, i tink the police has
their way to retrieve the sms.. is shown on crime watch b4 that a
person deleted all the picture in a memory card, but the expert in
police force are still able to retrieve the picture..
